1.54 inch TFT lcd capacitive touch screen st7789 IPS 240*240 3 wire 9bit 8Pin display module(1pcs))

Capacitive touch drive IC: FT6236G

The driving timing of this display screen is 3-wire 9BIT . If the main control does not support it, GPIO can only be used to simulate

Note: The display driver is not a standard protocol, and there is no DC for 3-wire 9bit. The first bit is used as the DC.

Many microcontrollers do not support hardware in this mode, so they can only use GPIO to simulate timing,

The speed will be relatively slow. Mind if you consider paying carefully.

interface

01: GND power supply ground positive pole, supporting 3 3V and 5V inputs

02: When the VCC power supply is 3.3W, U3 is empty and J1 is short circuited. When the power supply is 5V, connect [3, J is disconnected

03: SCL serial clock signal

04: SDA serial data input/output signal

05: RES reset signal

06: DATA1 3-wire 2data data pin datal, can be left blank without connection

07: cS LCD chip selection signal, effective at low level

08: BL backlight enable pin, high-level backlight on, low-level backlight off
